In my last email to Jack in reference to how would the WA22 compare to my maxxed WA2 in terms of sound and power. His response-


"Compared to WA2, the 22 has higher power and bigger sound.

You can use either input with any output. However, the amp operates in balanced mode on a balanced input only. I would highly recommend that you use a balanced source to take advantage of the design."



I use my WA2 with Denons, Grados, Beyers, Senns, Ultrasones and it drives them all with authority.

I really can't see the WA22 being shy on power. Quite the opposite.

Yep, especially if you upgrade the power tubes to something that delivers a bit more than what the stock tubes can offer. When I asked Jack about the WA22's power compared to the WA6SE, I'd have to guess that he was referring to both units with the stock tubes.

I am just saving up a bit more money until I can order the WA22 (for my D7000s) and I have absolutely no reservations about hitting that order button

Speaking of rectifier tubes for the WA22, I'll ask my question here. Please pardon my technical ignorance, my only hope is that someone else had the same question but was too embarrassed to ask.

I've read quotes from Woo themselves they prefer to run this beautiful unit from a balanced source. Running the WA22 from a balanced source, plus my limited knowledge of value electronics, doesn't that make the rectifier tube's job in the circuit redundant? Which is too take a single-ended signal and make a high-quality balanced signal? Shed some light on this please!

I have a great single-ended source coming but now that I'm looking at going balanced either with headphones or stats, I'm kind of kicking myself in hind sight. Previously I had believed the biggest different in going balanced would be rewiring the headphones and not worrying too much about the source. Ultimately I can't fret too much about upgrading my source now as it's the character I like at the price I was willing to spend with out going into debt. Now its just a matter of educating myself about this never-endingly interesting hobby.

a rectifier tube is used to convert AC to DC power - thus, its job can never really be redundant

Ah, its part of the PS, I see. Then how are the single ended inputted converted to the balanced signals fed to the headphones in the WA22? Some sort of solid state class A method?

Single ended input gives you single ended output via any of the jacks you use. It doesn't use a phase splitter to convert SE into balanced. Fortunately single ended WA22 sounds quite nice, with better separation and bigger soundstage than my single ended WA6.

if i had a desktop system with a soundcard (auzentech hd hometheater), and i were to get my denon d7000s rewired from SE to BAL, and got the WA22, if there anything i can do, there no mod or adapter, to have the soundcard put out a balanced signal?

D7000 = 700-1000$
WA22= 2000$
source = 200$
i don't get it
Crap in + high-end amp + high end headphone = Crap out
change your source

no, use the Auzentech SC as a transport instead (SPDIF from the SC) and add a nice balanced DAC to feed the WA22.

You can use an adapter like this one.
post #146 of 322
the transport was a consideration, so that my 5.1 speakers could handle analog out and then use digital out to a dac, and i could just switch when needed.
is there a dac thats generally considered the leader and stands out from the crowded market, that would match a wooaudios balanced quality, or is there a spread of ones considered top end and ill go research from there...

for using an adapter as a consideration, thanks for that link, i contacted them about pricing and such, but i wanted to ask someone outside the company....does using an adapter still mean its a unbalanced signal thats converted to balanced only because someone has no choice, they are only converting for the need (hardwares signal-in is balanced only) to but not quality.....OR does using an adapter somehow work a magic that removes the 'chaff' from an unbalanced signal and makes it a true balanced signal, restoring the 'shine'?
the company said that its done with a transformer, and they use the best one available, but that doesnt tell me actual specs and if its a true balanced, or balanced just for the sake of someone needing balanced-in on some hardwares input...

thanks again for the reponses, and should someone wonder why a soundcard with the wa22, i already have another balanced piece of hardware intended with the wa22, but i wanted to know if there was a way to have a htpc system put out a balanced signal for headphones too...

That's why I ordered mine with 2 XLR inputs no RCA input. There is delay on the WA22 delivery date. About 20 days
